    Abstract: An operation method performed at a nonvolatile memory device may include receiving a program command and an address from an external device through a data signal (DQ), receiving a specific pattern from the external device through the data signal and a data strobe signal (DQS) synchronized with the data signal in a pattern period, receiving user data from the external device through the data signal and the data strobe signal in a data period, and selectively performing a program operation on the user data or a recovery operation based on a determination of whether the specific pattern matches with a particular pattern. A rising edge or a falling edge of the data strobe signal may be aligned with a left edge or a right edge of a window of the data signal in the pattern period.

    Abstract: A developing apparatus includes an organic photo conductor, an OPC frame part to support the organic photo conductor, a developing roller to develop a latent image formed on the organic photo conductor by supplying a developer, a developing roller frame part to support the developing roller, a developer storing part to store the developer and provided with a supplying opening through which the developer is supplied to the developing roller, a spacer removably interposed between the OPC frame part and the developing roller frame part and spacing the OPC frame part from the developing roller frame part such that the organic photo conductor and the developing roller do not contact each other, a leakage preventer removably attached to and sealing the supplying opening, and a connecting part to connect the spacer with the leakage preventer. Thus, the spacer and the leakage preventer are capable of being removed simultaneously.

    Abstract translation: 显影装置包括有机光导体，用于支撑有机光导体的OPC框架部分，通过供应显影剂显影形成在有机光导体上的潜像的显影辊，支撑显影辊的显影辊框架部分， 显影剂存储部分，用于存储显影剂并且设置有供给开口，显影剂通过该供给开口被供应到显影辊;可拆卸地插入在OPC框架部分和显影辊框架部分之间并将OPC框架部分与显影辊隔开的间隔件 使得有机光导体和显影辊彼此不接触，可移除地附接到密封供应开口的防漏器和用于将间隔件与防漏器连接的连接部。 因此，间隔件和防漏器能够同时移除。
